DC Power Circuit Breaker for M320 Routers

 

Each DC power supply has a single DC input (–48 VDC and return). To enable you to operate the router in any configuration without upgrading the power infrastructure, we recommend that you use a dedicated customer site circuit breaker rated for 60 A (–48 VDC) minimum for each power supply. If you do not provision a 60 A (–48 VDC) circuit breaker, provision a customer site circuit breaker for each DC power supply rated for at least 125% of the continuous current that the system draws at –48 VDC, or as required by local code.
